` OIL-BURNER TIP.

Specication oi Letters Patent.

Application filed May 16, 1911. Serial No. 627,503.

Patented/oct. 31, 5.1911.

To all whom 'it may concern:

Be it known that I, CARL BHIm, a subject of the Emperor of Germany, residing in the city and county of San Francisco and State of California, have invented new and useful Improvements in Oil-Burner Tips, of which the following is a specification.

This invention relates to tips, and particularly for an improved tip for oil burners.

The object of the present invention is to provide a substantial, durable, integral tip of special design, and so formed as to produce a peculiarly shaped tongue of ame; and to provide a burner involving special details of formation with a purpose of enhancing the mixture of the combustible fuel issuing from the burner.

The invention consists of the parts, and the construction and combination of parts, as hereinafter more fully described and claimed, having reference to the accompanying drawings, in which- Flgure l 1s a perspective view.of-a burner tip. Fig. 2 is a longitudinal, central section through the burner tip. Fig. 3 is a section transversely through the burner and its orifice. Fig. 4 shows a similar section of a burner tip having a different orifice.

The purpose of the present invention is to devise a discharge tip adapted to be attached to various forms of oil burners, a part of one being indicated'in dotted lines at 2. The tip is illustrated in the perspective view, Fig. 1, as having an internally threaded stem 3 and a transverse face 4, which may be rectangular inplan view, and is preferably in the form of a segment in side View.

The eiiiciency of the present tip is derived from the peculiar formation of the fuel discharging orice 5, which is formed longitudinally in the face 4, and which communicates wlth the interior 6 of the tip. As shown in Fig. 2, the interior is provided with a hemispherically curved end portion 6', terminating comparatively close to the lane of the face 4, and expands conically 1n the stem 3.

In forming the discharge orifice 5 in the face 4,. a suitable tool is used which will lon itudinally channel the face 4 of the tip, andg form an opening or slothaving a curved bottom surface; the orifice 5 being cut suiiiciently deep to intersect the curved portion 6 within the tip, that is, I form a out longitudinally across the lface 4 of the tip, the arc of the cut intersecting and overlapping a portion of the arc of the chamber 6 in a plane approximately the centerl of the tip. This peculiar relation of the external opening or-orice 5 and the chamber 6 forms acute, sharp cutting edges at the points a of intersection, Fig. 2.

I have found by actual practice with tips constructed in this manner that an extremely efficient mixture of the iiuids issuing fro'm the chamber 6 is obtained; and that by varying the radius of the orifice 5 a different shaped tongue of flame is roduced; and also by varying the width of t orifice 5 a different shaped tongue of flame is produced. If it is necessary to have a tip which must produce a comparatively longl tongue-like flame, the orifice 5 is cut .wider and the arc of the Icut is ofcomparatively small radius. If a very flaring or fanshaped flameis to be produced, due to the peculiar construction of the fire-box in which the tip is being used, then the orifice 5 is formed with an arc of considerably greater radius and this produces thedesired an-shaped flame as the fuel issues from the tip. p

Having thus described my invention,

what I claim and desire to'secure byLetters Patent, is-v A tip .for oilburners comprising a stem and a head extendin transversely and at` one end of the stem, te stem having a bore Vthreaded at one end and tapering toward its other end and terminating in a hemispherically curved portion adjacent the plane ofthe outer face of said head, and

said. headv having a longitudinal slot, the

base of which is curved and intersects the said curved portion of the stem bore, formin acute edges at the points of intersection.

n testimony whereofI have hereunto set my hand in the presence of two subscribing
